Tubeless road tyres offer less rolling resistance than standard tyres and tubes. You get a faster rolling and accelerating wheel and almost eliminate the risk of punctures- and if you do get something sticking through your tyre dont worry Magic milk will seal holes up to 6mm in size.

Magic Milk tyre sealant works with tubeless road tyres and inner tubes, we even use it on our CX gravel bikes. It seals holes in tyres and inner tubes equally quickly and goes on protecting for months and months without drying out

Tubeless tyres have been around longer than most people think, they've been around on motor vehicles since the mid-fifties and the first effective tyre liquid tyre sealant was developed by UK-based OKO way back in 1978. For motorbikers, quad riders, long-distance lorry drivers and fleet managers the world over OKO is the go-to brand for protecting their tyres and keeping them on the road (or off-road). OKO is the number one tyre sealant brand in the heavy off-road market. If you run 'heavy-plant', tippers, 30-tonne quarry lorries with tyres costing 10k+ a corner then you trust OKO to keep running smoothly. With the proven ability to seal holes in big tyres up to 20mm in size with their thickest formulation, we'd trust them as well. In fact, that's exactly why weve teamed up with OKO. Theyre the tyre sealant experts.
